Do you have to drill holes in external walls at an angle?

Wheety

I installed an aerial and forgot to drill the holes for the aerial bracket at an angle.

Do I need to fill the holes and start again?

Or is that just for running cable through the wall?

I didn't have to run cable through as I used existing cable.

Just in case it's not clear what I mean, the angle is to stop water running in.

No, you're fine. No water cant get through those holes as they're tight with the fixing screws in them. The hole that the cable goes through can be at an angle pointing down so water can't ingress in but it's not that important anyway as normally the hole on the outside is sealed with silicon anyway.

If the hole will break through the outer fabric of the building the angle of the hole should be drilled upwards into the interior of the house not downward.

But with the current hole just make sure that you run the cable to one side of the hole and U-loop the cable below the entry hole and secure at lower points so that any water drips off the low point rather than being channeled directly into the drilled hole.

Oops sorry just noticed its the arial not the cable drill straight and seal.

Thanks for the replies.

The drill only seemed to meet resistance for an inch or so and then there seemed to be a gap. I presume they are cavity blocks. That's why I'm worried about the water getting in. But the screws I used are in rawlplugs so I'm hoping there is no way for water to get in. Should I use some sealant around the bracket too?

No harm in using a bit of sealant if it’s handy.
